CHARLES L. HILDRETH, OF LOWVELL, MASSACHUSETTS, ASSIGNOR TO THE LOWELL MACHINE SHOP, OF SAME PLACE.

SEPARATOR MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 498,265, dated May 30, 1893.

Application filed February 10, 1893. Serial No. 461,727- (No model.)

To all whom it may concern: Be it known that I, CHARLES L. HILDRETH, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Separator Mechanisms for Ring-Spinning Frames, of which the following isa specification, reference being had therein to the accompanying drawings.

This present invention relates to the devices that are employed in ring-spinning frames for supporting and operating the separators which sometimes are interposed between the spindles of such frames for the purpose of restricting the ballooning of the yarns being spun, and for preventing the said yarns from striking against one another in consequence of such ballooning.

The main object of the invention is to pro vide a simple and practical improved arrangement and combination of supporting and operating devices whereby not only shall the separators be moved vertically simultaneously with the ring-rail, and also in the same direction as the latter, but they shall be moved through a traverse of less extent than the ring-rail, so as to remain in proper position relatively to the various parts, the use of adjustable stops to determine the lowest limit of the descent of the separators and of adjustable feet on the separator-rods to determine the highest point of the traverse of the separators thereby being rendered unnecessary; and wherein shall be embodied improved means for enabling the traverse of the separators quickly and conveniently to be shifted higher or lower as desired with relation to the thread-board, spindles and ringrail, without any resulting variation in the extent of such traverse. The omission of the adjustable stops and adjustable feet secures a simplified and more reliable mechanism. Capacity for effecting a vertical shift or translation of the traverse of the separators is highly desirable in a separator-mechanism in order that the requirements of the different conditions under which one and the same spinning-frame is used may be met properly, and also in order to enable the separator.- mechanism to be fitted to the different sizes of ring-spinning frames that are in use without it being necessary to keep on hand a stock of various sizes or lengths. Separatormechanisms of the same structural type as that to which the invention relates, as heretofore proposed to be built, usually have been devoid of capacity for the said vertical shift or translation. Where no provision for adjustment exists in the separator-operating devices, jt becomes necessary for the maker thereof to provide different lengths of separator-rods, or a like supply of different sizes or lengths of some other part or parts, in order to enable the traverse of the separators in a given spinning-frame to be varied by an interchange of parts, and also in order to enable the separator-mechanism to be fitted to the different sizes of spinning-frames that are built.

Another object of the invention is to provide-an improved form of the pivotal connections whereby the separator-rail is mounted at the upper ends of the separator-rods.

The invention consists, first, in certain features of improved construction and combination, embracing adjustable devices of an improved and novel character for enabling the traverse of the separators to be shifted or translated vertically as required, without the extent of such traverse being altered.

It consists, further, in an improved construction of the pivotal connections between the separator-rail and its supports.

The invention first will be described with reference to the accompanying drawings, in which are represented the best embodiments thereof which so far have been devised, and p then will be particularly pointed out and distinctly-defined in the claims at the close of this specification.

In the drawings, Figure 1 is a view in front elevation showing a portion of a ring-spinning frame with the preferred embodiment of the invention applied thereto. Fig. 2 is a view in vertical section on the line 22 of Fig. 1. Fig. 3 is a view in side elevation of certain of the parts whichare. represented in Fig. 1, and which are more immediately involved in the first portion of my invention. Fig. 4 is a view in plan of the parts which are represented in Fig. 3 but with a portion thereof in section in order to show more clearly the IOG construction. Fig. 5 is a view in vertical section on the line 5-5 in Fig. 3. Fig. 6 is a view in vertical section on the line 6-6 in Fig. 3. Figs. 7 and 8 are views similar to Fig. 6 showing modifications. Fig. 9 is a view in rear elevation of the upper end of a separator-rod, the socket affixed thereon, part of the separatoarail, a separator, and abracket mounted on the separator-rail. Fig. 10 is a viewof the same parts, mostly in side elevation, but with the separator-rail in section. Fig. 11 is a view in side elevation of the socket which is afiixed to the upper end of the separator-rod. Fig. 12 is a view in horizontal section on the plane indicated by the line 12--12 in Fig. 11. Fig. 13 is a view of the socketfrom the left-hand side in Fig. 11.

In Figs. 1 and 2, 1 is the roller-beam, 2 the thread-board hinged thereto as usual, 3 the finger-boards hinged as usual to the threadboards, 4 the yarn-guides secured to the finger-boards, 5 the yarns passing from the yarnguides 4 to the bobbin 6, through the travelers 7 on the rings 8 supported by the ring-rail 9, 10 the spindles on which the bobbins are mounted, 11 the spindle-rail, 12 the lower or guide-rail, 13 the lifting-rod for the ring-rail, 14 the shoe or foot at the lower end of the said rod, 16 the cross-shaft arm carrying the stud 15, the latter either acting directly upon the under face of the said shoe or foot or being provided with the roller 151, Fig. 6, which acts against the said face of the shoe or foot 14 and fits upon stud 15, it being held in place thereon by the thin-headed screw 152, the threaded part of which enters a threaded hole in the end of the stud.

At 17 is shown the cross-slot in the free end of the said cross-shaft arm 16 in which the said stud is adjustably mounted.

153 and 154 are, respectively, the washer and nut which are slipped upon the threaded end of the stud and on the side of the arm 16 opposite that on which is located the roller 151, and by means whereof and the collar155 011 the stud the latter is clamped in the desired position of adjustment in the slot 17.

At 18 is shown the cross-shaft on which the said arm 16 is secured, the said cross-shaft turning in bearings in brackets 19 (only one of which brackets is shown) and being caused to rock by usual means for the purpose of moving the ring-rail up and down, the crossshaft being in practice usually provided with an arm 181 on which is adjustably mounted a weight 182 for counterbalancing the parts which are operated by the arm 16.

All of the foregoing parts may be of any usual or preferred construction.

At 20 in Figs. 1 and 2 the separators are shown, and at 21. the separator-rail on which the separators are mounted.

At 22 is shown a rod by which the said rail is supported, the said rod, by preference, being tubular, and it being held in upright position by guides in a stand or bracket 23 which is secured by bolts 24, 24, and nuts 241, 241, to the rail 12. Provision is made as follows for actuating the rod 22 from the cross-shaft arm 16 simultaneously with the ring-railand inthesame direction butthrough a traverse of less extent, or for actuating similarly an equivalent support for the separator-rail. On the lower end of the rod 22 is affixed a shoe 25 having by preference the shape of an inverted T and formed with a fiat under surface. The arm 16, see particularly Figs. 2, 3, 4 and 5, is formed with avertical screw-threaded hole 26 therethrough at a point between the cross-shaft 18 and the stud 15, and through this hole is passed a screw-threaded stud or pin 27, the thread thereof fitting the hole, and the said stud or pin having nuts 28 thereon, one of the said nuts being above the portion of the arm 16 through which the stud or pin is passed, and the other nut being below such portion. By

means of these nuts the stud or pin is locked after having been turned to adjust it transversely of the arm into desired position, the nuts being screwed up so as to bear against the opposite sides of the portion of the arm through which the stud or pin is passed. The stud or pin 27 is intended to support the separator-rod, or equivalent part or carrier for the separatorrail and the parts carried thereby, and for this purpose the lower face of the foot or shoe 25 may, if desired, rest upon the upper end of the stud or pin. I prefer, however, to interpose between the shoe and the upper end of the stud or pin a swiveling cap piece 29, the same having a flattened upper surface to fit against the bottom face of the foot or shoe. The cap-piece may be applied variously to the upper end of the stud or pin. In the drawings it is shown formed with a concavity in its under face to receive the up per end of the stud or pin, which fits loosely into the cavity. Preferably, the upper end of the stud or pin is partly spherical and the concavity in the cap is correspondingly shaped.

In consequence of having the stud or pin 27 applied to the arm 16 at a point between the cross-shaft l8 and the stud 15, less movement will be communicated to the separatorrod (or equivalent carrier) and separators than to the lifting-rod. The distance from the axis of the cross-shaft at which the stud or pin is applied to the arm 16 is such as will secure the desired ratio between the extent of the up and down movement of the separator-rail and separators and that of the corresponding movement of the ring-rail and rings.

In the drawings, as shown, the movement of the separator-rod and separators is intended to be about one-half as great as that of the lifting-rod and ring-rail. For the purpose of shifting vertically the traverse of the separators without varying such traverse in extent, the height to which the upper end of the stud or pin 27 extends above the upper surface of arm 16 is varied by efieeting suitable rotation of the stud or pin in the hole 26. The stud 15 and. stud or pin 27, it will be seen, are independently adjustable cross-wise of the arm 16, thereby enabling the traverse of the ringrail to be shifted vertically as required, by making properadjustment of the stud l5,without such adjustment itself aifecting the traverse-of the separators, and also enabling the traverse ofthe separators to be independently adjusted or shifted verticallyat any time relatively to the traverse of the ring-rail.

The devices shown in the present case for transmitting movement from the arm 16 to simple. They are also comparatively inexiseparator-rail, the .separator-rod,and the foot -or shoe at the lower. end of'said rod, of the arm 16, the screw-threaded stud or pin passedftherethrough, and the swiveling cap on the upper end of the pin and acting against the face of the foot or shoe of the separator-rod, I

pensive, and, inasmuch as all desirable lengths of screw-threaded pins like that shown in the drawings are commonly kept'in stock by manufacturersfor various purposes, a longer or shorter pin could be substituted for another at almost no expense. Repairs may be readily and cheaply made.

In practice one or both of the nuts 28 and 28 which are placed on the stud or pin 27 for the purpose of locking the same in adjusted position may be omitted. The hole in the arm 16 through which the stud or pin 27 passes,instead of being provided with an internal screwthread into which the external thread of the stud or pin will take,'as hereinbefore described, may be plain, as in Fig. 7. In this case the stud or pin will be held in desired position-onthe arm 16 by the nuts 28 and 28, and adjustment of the stud or pin in the direction of its length may be eifected by rotating the nuts thereon. The construction may be further modified by omitting the nut 28which is placed underneath the arm 16, as shown in Fig. 8, thus leaving the nut 28 which is located on the upper side of the arm to sustain the stud or pin. in position. For the purpose of pivotally supporting the separator-rail upon the separatorrods, I fit upon the upper end of each of the separator-rods a socket or support 30, see Figs. 9 to 13, which is held in place by means of a clamping screw 31 that passes through a threaded hole in the socket-or support and takes bearing by its end against the side of the separator-rod, the upper part 32 of the socket or support having therein a hole 33 which receives a pin 37 projecting from a bracket 34 that is affixed to the separator-rail. The said bracket 34 is formed with a lip 341 that fits against one of the edges of the separator-rail to keep it from turning on the separator-rail, and it is held to the latter by means of the screw 35. It is formed with an ear or lug 36 that carries the pin 37. The part 32 of the socket or support 30 is formed at its front with a rest 38 serving as a support for theseparator-rail when it has been turned forward into the working position thereof and it is formed on its top with a similar rest 39 serving as a support for the separator-rail when it has been turned into the idle position thereof, the part of the said socket intermediate the rests being so formed as not to interfere with the free movement of the separator-rail upon its pivots in being turned from one of its positions to the other. The rests 38 and 39 preferably are formed, as shown,

reference to the path of movement of the separator-rail and against which the rear surface ranged to take a bearing against the rests 38 and 39, and I consider this to be the equivalent of the arrangement shown and above de scribed. the separator-rail are extremely practical and I claim as my iuveution 7 as'plane surfaces disposedeccentrically with 1.
